i think you are missin a "not" in your sentance

and iam not sure abut the fourccs here, this format is simply inefficient
to store 4bit rgb, is it used in the wild?
if not (its just for ffmpegs test lavfi test system we can just pick any
random fourcc and treat it like some ffmpeg internal thing)
either of your choices would do for that
